It is obvious to any experienced radiologist that the vantage point from which we view something powerfully shapes what we see. For example, a metallic foreign body in the subcutaneous soft tissues may be easy to spot by plain radiography, but a lower-density foreign body such as a wooden splinter is likely to be so radiolucent that it cannot be detected on radiographs but proves easily detectable by ultrasound, where acoustic impedance, not physical density, is the key imaging parameter. Likewise, a lesion such as a meningioma that initially appears intra-axial on transverse images may prove to be obviously extra-axial on coronal or sagittal reformatted images. To stand the best chance of seeing things for what they really are, we need to look at them from the appropriate perspective.
